Description
Technical Field
The utility model relates to a valve test technical field especially involves electric formula high temperature device that generates heat.
Background
Valves are mechanical devices that control the flow, direction, pressure, temperature, etc. of a flowing fluid medium, and are essential components in piping systems. Valve leakage can lead to production abnormal operation, and valve seal inspection is also called valve leakage detection, and valve leakage detection must be carried out when the valve leaves a factory.
The sealing performance of the sealing element in the butterfly valve is high in temperature, so that the butterfly valve used in high-temperature environments such as a high-temperature flue gas pipeline and the like is subjected to high-temperature sealing performance test before leaving a factory. The medium for testing the leakage amount of the butterfly valve is gas, the medium needs to be heated to about 500 ℃ by using a heating device, and the conventional heating device has high energy consumption and low heating speed, so that the conventional heating device needs to be improved.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that will solve is: the heating device has good heating effect and low energy consumption.
In order to solve the technical problem, the utility model discloses a technical scheme as follows:
the electric high-temperature heating device comprises a heating chamber, a heating element, an air inlet pipe, a fan and an air supply pipe, wherein the heating element is arranged in the heating chamber, and the fan blows an external test medium into the heating chamber; a plurality of guide plates are arranged in the heating chamber; the air guide plates are arranged along the length direction of the heating chamber, one of the two adjacent air guide plates is fixed at the top of the heating chamber, the bottom of the air guide plate and the bottom of the heating chamber form an air passing hole, the other air guide plate is fixed at the bottom of the heating chamber, and the top of the air guide plate and the top of the heating chamber form an air passing hole.
Compared with the prior art, the beneficial effects of the utility model are that: the guide plate guides the retention time of the test medium in the heating chamber 11, so that the test medium is fully and uniformly heated, the heat exchange rate is improved, the heating speed is high, and the energy consumption is low.
Drawings
In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings used in the description of the embodiments will be briefly described below.
Fig. 1 is a sectional view of a heating unit.
Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Examples
The electric high-temperature heating device converts electric energy into heat energy and comprises a heating chamber 11, a heating element 13, an air inlet pipe 14, a fan and an air supply pipe 15, wherein the heating chamber 11 is coated with heat preservation cotton 12, the heating element 13 is arranged in the heating chamber 11, an external test medium is blown into the heating chamber 11 by the fan, and the heating medium is sent into test equipment by the air supply pipe 15. The heating element 13 is an electric heating tube made of stainless steel 310S. Heating element 13 includes seamless heating pipe and heating wire, and the heating wire is installed in seamless heating pipe, and it has the good magnesium oxide powder of heat conductivity and insulating nature to fill between heating wire and the seamless heating pipe, and when the electric current passed through high temperature resistance wire, the heat of production was passed through crystallization magnesium oxide powder and is to heating pipe surface diffusion, and the retransmission goes in being heated air, has reached the purpose of heating. The two ends of the seamless heating pipe are sealed by silica gel ceramics, the structure is advanced, and the heating effect is excellent. A plurality of flow deflectors 16 are arranged in the heating chamber 11. The guide plate 16 is arranged along the length direction of the heating chamber 11, one of the two adjacent guide plates 16 is fixed on the top of the heating chamber 11, the bottom of the guide plate 16 and the bottom of the heating chamber 11 form an air passing hole, the other guide plate 16 is fixed on the bottom of the heating chamber 11, and the top of the guide plate 16 and the top of the heating chamber 11 form an air passing hole. The guide plate 16 guides the residence time of the test medium in the heating chamber 11, so that the test medium is fully and uniformly heated, and the heat exchange rate is improved.
Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
